MORTAR SPREADER.

Application filed April 26, 1924. Serial No. 709,182.

My invention relates to improvements in mortar Spreaders, or mortarspreading mechanisms, in which there is a mortar ejector, or container,provided at one end with .an intake opening having therein a feed pipefor connecting with a stuffing machine and having at its opposite end aslot, or clon gated opening, and a trowel hinged to the ejector near theslot, the ejector having two sections or members (a front or top sectionand a rear or lower section) pivoted together near the intake-openingand having their opposite ends connected by two bolts for adjusting thewidth of the slot through which mortar may be discharged and spread [bythe trowel.

The object of my improvements is to provide time and labor-savingmeansfor ap-.

plying mortar to lath, or other surfaces. I

I attain this object by means of the mech- 'anism illustrated in theaccompanying draw-' ing, in which- Fig. 1 is a top plan View of myimproved mortar spreading mechanism together with a fragmentary sectionof lath and plaster as the latter would appear when applied to the lathwith my improved mechanism;

Fig. 2-a view of the lower edge of Fig. 1 without the lath and plaster;

Fig. 3a longitudinal sectional view taken on the line 3, 3, of Fig. 1;and

Fig. la cross section taken on the line 4, 1, of Fig. 1.

Referring to the drawing in detail 1- The reference numeral 2 representsthe ,front or top section or member of the mortar ejector (i. e., themember nearest the operator when in use). Said member 2' is provided,near the discharge end of the ejector, with two openings 3 and has eachof its side edges bent backward or downwardly at a right angle to thetop portion of the member to form a flange 2 each having, near theintake end of the ejector, an opening 1.

At the discharge end of the ejector member 2 has its end edge bentdownwardly at 2" and connected by ahingefi, having a ball or pin 7 withthe upturned edge 8' of the trowel 8 having a handle 9 connected withthe trowel by a bracket 10. The rear or lower member 11 is provided,near the discharge end of the ejector, with two openings 12, and has itsside edges bent forward or upward at a right angle to the bottom portionof the member to form flanges 11' ber 11 has its end edge 11" bentforward or upward whereby a slot or elongated opening 14 is formedbetween the edge 11" of member 11 and the adjacent edge 8 of the trowel.

At the intake end of the ejector the members 2 and-11 are pivotallyconnected by two rivets 15 arranged in the openings 4 in the flanges 2',and in theopenings 13 in the flanges 11.

At the members are adjustably connected by two bolts 16 arranged in theopenings 3 in member 2 and in openings 12 in member 11 and provided withthumb nuts 17 A feed pipe 18, forconnection with a stuffing machine, hasone end arranged in the intake end of the ejector and is provided withtwo openings 19; Arranged in the pipe 18 is a shut-ofl comprising a diskor shutter 20 mounted on ashaft 21 ar-' ranged in the pipeopenings 19'and provided with a handle 22.

To spread mortar on lath by means of my improved mortar spreadingmechanism, the operationis as follows: i

The feed pipe 18 being connected with a suitable stuffing machine theoperator holds @the trowel in one hand. and theejector in .the otherhand with the mortar spreader against the lath. Mortar may thenbeforced,

by a stufling machine, through the feed pipe into the ejector and as itpasses through the slot thev ejector is moved endwise in the directionindicated by the arrows on line 4:, 4:, Fig. 1, whereby the mortarpasses under the trowel and is forced against and between the lath 23 asindicated at 24 in Fig. 1 of the drawing. The spreader may be operatedeither horizontally or vertically.

The flow of mortar into the ejector may be retarded or stopped byturning the shutofi handle 22 or by slowing down or stopping thestufling machine.

If the mortar has a tendency to flow slower through the ends thanthrough the middle of the slot 14, a diverter may be so arranged in theejector as to partially divert the flow of mortar through the center ofthe ejector.

To prevent mortar escaping at the ends of the trowel the latter may bemade longer discharge end ofthe ejector the than the. slot. by eithermaking, the trowel longer than; the width. of the: ejector or. by

making the slot shorter than the width of the ejector.

The width of the siot 'may'be var-ied byscrewing the nuts 17 in or out.

The feed pipe and stufiing machinesh'ould' be connected by a flexible.pipe.

The mortar ejector and the trowel may be, adj ustably. connectedinsuch.manner. that. when. the. mortar ejeeton isheld. against; and slid on.the: lath. (or other; surface. on. which mortar is. to. bespread), the.trowel will. be the. desiredi thickness off themortar. away from. thelath. The. adjustable. connection. between; the: trowel and: ejector;could be made. in. any, suitable. manner. One. way would he, to, hingethe trowel. to, a. piece; of sheet metah. other; than. part2, and. then.

slidably connect. it. with. part 2; by bolts.

arranged l in perforations; forms d. in part. 2f

and in the part hinged to the trowel, the.-

perforations in; one oi, the. parts. being 7 slotted. so as to. permit.a vertical. movement of one part-witl1. relationpto. tliEBzOtll-I pant.

The =mortar; ejector; may. be. a. rigid. frame.

composed of one: or. more pieces-,. instead. of. two pleces. PlV-OlZBdtogether as: shown, 1n

whichcase. the: width off. the. slot; could. be. Varied by means of: an.attachment ELCljilSta-- bly connected with: the-ej ector on. either sideon lip of. the: slot. @r. the. end. portion. 27

of member 2. could-be: a separate; piece; and.

llZIVG'itS upper. edge. hinged to the. member 2.

whereby its lower edge couldabemoved' in.

or out, to.- make the: slot narrower. or. widen and be. adjust-ably.secured. in. the desired. position.

As there. are. other: minor. changes that might be. made in: theconstruction. of my improved. mortarspreading mechanisml do notw-ishtobelimitedto. the particulan construction shown and described.

Having. thus described my, invention, what I claim asnew and. desire-tosecure by Let.- ters; Patent, .is-:-

In a mortar spreading. mechanism of! the character. described} a.mortar ejectorhaving an; intake: opening; and a. discharge opening andhaving: an: upper member. and. a lower member pivotedl together at thein.- take end, eachmember. havingnear. the discharge cnd. two openings,the openings. in the. upper member registering with. the openings. inthelower' member, two bolt-s arranged in the openings and extendingthroughthe. ej ecton and adapted. to regulate thev size of the. discharge.opening, and. a trowel provided. with a handle and. having one edgehinged to the upper member above thedischarge opening.

Ql In a mortar spreading mechanism of the character described, a mortarejector having at one end an intake opening and at its opposite end adischarge slot and comprising an upper member and lower member pivotedtogether at the intake end, the lower member having on each sidethereof. an upturned flange, the upper member having. on. each. sidethereof a down turned flange,,the flanges of one member slidably fittinginside. 0]; the flanges oi the other member, adjustable.- meansconnecting the discharge. end. of; the. members and adapted to controlthe. width. of the discharge slot, and ahand operated trowel providedwith a handle-andihaving one edge hinged to the dischargeend of theupper member above the. discharge slot.

3 In. a, mortar spreading mechanism of the; character. described, amortar ejector having an intake. opening and a discharge opening, said vejector comprising two members pivoted together at the intake opening,adjustable means. connecting the discharge endofthe. members and adaptedto control the" size of; they discharge opening, and a handloperatedtrowel provided with a handle andjhaving. one. edge. bent. upwardly andadjustablyconnected" with the ejector whereby mortar. passedthrough thedischarge open ingi will pass under and be spread by the trowel.
